(a) Each component of a pipeline must be able to withstand operating pressures and other anticipated loadings without impairment of its serviceability with unit stresses equivalent to those allowed for comparable materials in pipe in the same location and kind of service. However, if design based upon unit stresses is impractical for a particular component, design may be based upon a pressure rating established by the manufacturer by pressure testing that component or a prototype of the component.

(b) Each component of a pipeline including, but not limited to, valves, flanges, fittings, tapping, metallic components, branch connections, extruded outlets, supports and anchors, and compressor stations, among others, shall meet the standards set forth for such components in Subpart D of 49 CFR Part 192, which is hereby incorporated in these rules.
